Abstract

An attempt has been made to assess the Phytoplankton diversity of Purle pond water of Shivamogga city. During the period of investigation 38 species of phytoplankton representing four main taxonomic groups such as Chlorophyceae, Cyanophyceae, Euglenophyceae and Bacillariophyceae were recorded. Relative abundance of phytoplankton in Purle pond showed maximum of Chlorophyceae (33.3%), followed by Bacillariophyceae (23%), Cynophyceae (23%) and Euglenophyceae (17.9%). Microcystis aeroginosa, Merismopedia glauca, Euglena gracilis and Scenedesmus quadricauda were the common pollution indicators.
